Baby seats protect children from injury or death during collisions. There are three main types of child car seats, each designed for different ages (and sizes) of children. Firstly, rear-facing infant seats and convertible seats are generally suitable for babies up to 22lbs (about 10 kilograms), roughly from birth to 12 months. Next, forward-facing harnessed child seats are for children older than one-year of age and heavier than around 20lbs (9.1kg Lastly, a booster child seat is recommended when the child grows older and does not fit the forward-facing harnessed child seats. According to local regulations, anyone below the height of 1.35m will have to be secured with a child restraint.
